Three-dimensional analysis of facial morphology using moiré stripes. Part I. Method.

A system is presented for analysing facial morphology using moiré stripes. Faces are photographed with a moiré camera, the moiré stripes are entered into a computer, and the computer automatically analyses the dimensions of the face. Subtle differences between the right and left sides of the face appear as asymmetries in the moiré pattern and are easily identified. The method is useful for analysing maxillofacial deformities, for treatment planning, and assessment of postoperative results.
